opencv海思平台移植解决warning: ../../lib/libopencv_imgproc.so, needed by ../lib/libopencv_imgcodecs.so, not

1、opencv编译部分请参考：

2、编译过程中出现的错误查找网络自行解决；

编译过程中出现的错误因人而异，我遇到的错误是cuda和protobuf，关闭这两个编译选项即可。

3、交叉编译过程中出现：

warning: ../../lib/libopencv_imgproc.so, needed by ../lib/libopencv_imgcodecs.so, not found (try using -rpath or -rpath-link）

是因为编译后的opencv动态库自带路径[ ../../lib/libopencv_imgproc.so];

使用命令查看：readelf -d libopencv_imgproc.so | grep NEEDED
